ok yea its only the driver side tube tearin out of the diff, yea i think makin a truss that goes outside the springs would mean the truss is on the bottom of the axle?

I don't jump my truck 7' in the air but I do enjoy blasting around the dunes and really didn't wanna experience the same fate as my buddy so here's what I did to my 07 Cummins back in August:

12" Fox Remote Resi's are off the Cumdumpster

Lower shock mounts

Upper shock mounts

Bumpstops

Between the longer control arms, progressive bumpstops, and good shocks it was like a whole new truck in the dunes....worked AWESOME. The 800lb-ft was pretty damn nice too!! I just have to keep reminding myself that it's still my DD/towrig and that I need to take it a little easy!

I would have started with a 05+ hp60 as they used 3 3/4" 1/2" wall for a truck that heavy. And I bet you could of used the ford's radius arm mounts for the links just about.

I wouldn’t have, even if I didn’t already have this axle. We wanted kingpins and rebuildable hubs and the DRW 78-79 HP60 is the perfect width for this truck. Not sure what the WMS-WMS is on the new HP60s though. Besides the fact that the radius arm mounts in the newer Superduties use different bushings and would’ve required chopping up the existing control arms, building a truss around them would’ve been a nightmare, and the existing frame mounts may not have lined up(and those are not moving from where they’re at). The larger tube would’ve been nice but that’s the only benefit of the new HP60 over the one we used, and strength won’t be an issue on this one by any means.

Should be in the next few weeks. Axles just came out for gear installs, shock hoops and cross brace are 95% done, panhard bar will be in place in another couple nights, steering will be a piece of cake, bumpstops will go quick, etc. It's moving along pretty well and turning out great....I'll post more pics soon.

Looks like a good build so far. What kind of bracing is going on the upper coilover mount? Also what is the wall on the tubing your using?

The hoops and crossbrace are all .120" wall DOM, the crossbrace is dual tubes, the hoop mounts are gusseted top and bottom to the frame, etc. Plus there will be proper limit straps and bumpstops so the coilovers won't have to do more than basically support the weight of the rig.

What spring rates you running on the coilovers and are you guys shooting for a certain amount of travel. Then when you going back out to test this cause I want to be present.

I think based on the calculator we ended up at 500/600 for spring rates. The shocks are currently set at 6.5" of uptravel, 4" of which will be buttery smooth bump travel thanks to the airbumps that arrived at my house last night. Limit straps will stop droop at about 6", so about 12" travel. The rear uses pretty much all of the 14" travel shocks that are back there but still undecided what'll happen cuz Deaver isn't exactly cooperating. There was talk last night of 4 linking the rear with coilovers come springtime....

I don't think we'll be making it up to the dunes again this year to put it to the real test. I'm sure it'll get beat down lightly around here but there's really not much to work with, even with Michigan roads.

I see your using the fox shox's with the resi's. i go to silverlake quite a few times in the summer and i like to go fast across the dunes and do some off roadin with my truck was wonderin if the fox shox's are worth the money compared to some of the other brands??? a little off topic but it looks like you have some useage with these shocks

As of Thursday night the truck is together and back on the road. Still a few minor things to wrap up but the major stuff is all set and turned out great. I'll post pics soon.

They work great, especially considering how heavy the front end is on these things. My Rancho RSXs that came on the truck sucked hardcore for the dunes and were destroyed FAST. I made some other improvements at the same time as the shocks but the difference is night and day.

My plan is to do a SAS swap on my 99 silverado and kind of end up with something along the lines of what you have a decent off road but still able to drive it everyday.. looks like a lot of time and work.
